Type Function module

The module ASTRO converts various distance units commonly used in
astronomy. Normally, only the input to be converted is occupied and the
remaining inputs remain free. However, if several inputs loaded with
values, the values of all inputs are converted accordingly and then
summed.
1 AE = 149,597870 * 10 9 m
1 PC = 206265 AE
1 LJ = 9,460530 * 10 15 m = 63240 AE = 0,30659 PC

Output STRING(3) (compass readings)
DEG_TO_DIR calculates a direction (0 .360 degrees) into to compass rea-
dings. At the input DEG the direction in degrees is available (0 = North, 90
= East, 180 = South and 270 = West ). The output represents the directi-
on as String NNE. With the input N the maximum length of the direction in-
dication is limited. When N = 1, only in the 4 cardinal directions N, E, S, W
dissolved. If N = 2 between each another direction is inserted: NE, SE, SW,
NW. At N = 3 are also directions as NNO . are dissolved, with N = 3 a to-
tal of 16 directions are evaluated. The input L allows the switching of the
languages defned in the language setup. 0L = 0 means Default Langua-
ge, a number > 0 is one of the predefned languages. more info about the
pre-defned data types can be found at CONSTANTS_LANGUAGE.

for detailed information see data type CONSTANTS_LANGUAGE.
